The present invention discloses a composite prism based on an isosceles prism and a laser ranging telescope comprising the composite prism. The composite prism disclosed by the present invention comprises a first prism, a second prism, a third prism and a compensating prism. The first prism is an isosceles prism with three reflecting surfaces, the second prism is a roof prism, the third prism is a half-penta prism, and the compensating prism is a wedge prism. Through the composite prism, a telescope observation system, a laser emission system, a laser receiving system and a sighting and display system are reasonably integrated, so that a telescope features diversified performance and structural style, small size and convenient to carry.

A system and method for determining the wind force along the planned trajectory of a projectile are disclosed herein. A drone is flown along the expected path of the trajectory along a set heading. The drone is programmed to maintain the heading. As wind forces act upon the drone during its flight, the drone's electronic stability system provides automatic power and directional control to one or more motors that control the rotors and propellers that keep the drone aloft. By monitoring the changes in motor or drone state information over time in response to wind forces, the wind can be determined at various locations along the flight path. This information can be provided to a ballistics calculator to determine the launch heading of the projectile.

The invention relates to a long range optical device with at least a first visual optical path and a focusing device for focusing the at least first visual optical path. The long range optical device may also include a laser distance meter with a laser transmitter and a laser receiver, wherein a part of an optical path of the laser receiver extends in the at least first visual optical path to the objective lens. A region of the deflection of the optical path of the laser receiver out of the at least first visual optical path may be disposed on at least one optical component. The focusing device may be disposed between the at least one optical component for deflecting of the optical path of the laser receiver and the objective lens.
